How do I put a verb in present tense?

First, you find the infinitive form of the verb. This is the form you find in the dictionary. In English, this is the 'to' form of the verb e.g. to live, to work, to eat. Then, you see if the verb ends in ar, ir or er. Then you remove the ar, er or ir ending, and add the new ending. The choice of new ending will depend on what you're trying to say, for example, I live is vivo, because the infinitive form you find in the dictionary is vivir, and the first person ending, used for saying 'I' used with verbs that end in an ir is 'o', so you take off the ir ending and replace it with an o.
